Study summary
Questions
- Are some wallpaper groups more similar to one another?
- Fewer sets
- Higher 'similarity' ratings among exemplar pairs
- Are some exemplars more representative than others?
Exemplars per set?
Individual differences exemplars per set
Jaccard index as a metric of similarity/dissimilarity
- https://en.wikipedia.org/wiki/Jaccard_index
- \(J(A,B)=\frac{A \cap B}{A \cup B}\)
- \(0 <= J(A,B) <= 1\)
